2. The gantry longitudinal movement (x-axis) is guided by four high bearing capacity linear rolling guide pairs fixed on the bed, driven by dual drive, so that the gantry can be locked on the bed, enhancing the stability of the gantry during processing.
3. The CNC indexing head is fixed at one end of the machine base. The precision rotary bearing is adopted to realize the CNC indexing by AC servo motor through precision planetary reducer. 4. The drilling head is driven by the spindle servo motor through dual speed reducer and belt speed reduction. The drilling head is of ram type structure and adopts Taiwan precision spindle (internal cooling).
5. The axial feed adopts rectangular guide and AC servo motor to drive ball screw pair to realize fast forward / work forward / stop (delay) / fast backward and other actions. 
6. The machin is equipped with a cooling system, with internal cooling and external cooling functions, which can provide internal cooling for the tool to ensure the drilling performance and service life of the bit. The external cooling is mainly used to remove the iron chips on the upper surface of the material, so as not to affect the detection accuracy of the detection system
